的確なアドバイス(改善点)を出してくれたと思うところもある反面、不具合のような形で書き出された部分を確認したところ動作になんの問題もなかったという点が複数あった。 具体的には、「フッターのリンクを複数ユーザーがクリックしてもページが切り替わらない為、改善をしてください」という旨のレポートが出ていたが、実際に動作確認をしたところ正しいリンク先へ問題なく遷移している。ということがあった。
Provides some useful actionable information, but the support documentation is non-existent (the app points you to shopify for support, which points you back to the app...). I can't figure out how credits are distributed (monthly?) or if you can buy more ad-hoc. There's no information on what the difference is when specifying different target areas for a simulation (i.e. if I select to focus on cart and home page, does that mean I'm getting less quantitative or qualitative data?), there's no way to export simulation results, and there's no way to customize simulation shoppers (I had several searching for products I don't carry, and the recommendations were entirely unhelpful for providing alternative products. This was basically a waste of a credit since I can't provide information regarding my average shopper and ideal shopper). It's a cool concept, but kinda poorly executed.
Complete garbage!!! Did not understand my brand at all, searched for things we do not even sell, and insisted that our search was broken. Also, claimed our Checkout button is broken, when it is clearly not. I can go on BrowserStack and check it across multiple devices and browsers and clearly see that the Checkout button works. Maybe bots are too dumbs to figure out how to checkout. Overall, a complete waste of time. No one should ever pay for this app for any reason.
Does not work. I've been stuck on "scheduled" for 2 days. There is no customer support available. Not worth it.
Tremendous potential - but pay attention to your target audience, Shopify. Much of your value proposition centers around small to medium sized businesses who don't have access to highly experienced web teams - the very thing that makes Shopify so wonderful! These results from these simulations are useless without easy execution paths both understandable and executable for the average Shopify user.
The app has great potential, but without being able to customise Customer Persona's there is only a small benefit to its analysis. Our example is that our market is 95% University students who utilise this site for university merchandise, sport programs, club memberships and events and course equipment. Adding data to help fine tune the bots personas would significantly increase the effectiveness of the app to be tailored to the customer base that we have.
Very useful for identifying credible solutions to website flow, product analysis. Overall, very pleased with the problem-solving solutions provided. All suggestions have been valid so far.
Doesn't seem useful. The suggestions are very generic.
